witnesses UNITED STATES PATENT Utmost BENJAMIN \V. GRIST, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE PENNSYLVANIA IRON WORKS COMPANY, OF SAME PLACE.

VAPORlZER FOR GAS-MOTORS.

QPECIFICATION forming part of Letters Patent No. 545,125, dated August 27, 1895.

Application filed June 17, 1895. $erial No. 553,063. (No model.)

To all whom, it may concern:

Be it known that I, BENJAMIN W. GRIST, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Vaporizers for Gas-Motors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to gas-motors, and has especial reference to means for vapori zin ghydrocarbons or other volatileliquids for use as an explosive agentin such motors; and it consists in certain improvements in construction whereby the liquid is spread into a thin sheet and air in comminuted streams passed through the liquid and thoroughly saturated therewith and the excess of liquid returned to the source of supply, as will be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification, Figure 1 represents a vertical transverse section, and Fig. 2 atop plan view on the line 2 2, Fig. 1.

Reference being had to the drawings and the letters thereon, A indicates the lower seccess of liquid is discharged from the chamber 0 through passage cl and returned to the pump which supplies the liquid or to a suitable reservoir. The section A is also provided with an external annular flange c and an internal concentric seat f.

The upper section B of the casing is provided with an annular flange g, by which it is secured to the flange e of the section A by suitable bolts h, with a packing-gasket i interposed between the flanges, and near the upper end is an annular projection lain which are ports or passages Z, and upon said projection rests an annular cut-0ft valve m, which is provided with ports or passages n, which register with the ports Z. The valve 972 is axially movable upon its seat on the projection in to regulate the quantity of air admitted to the vaporizer.

Above, and resting upon the upper surface of the valve on, is an annular check-valve 0, which is inclosed in a chamber 19, formed by the annular cover g, which engages a screwthread '1' on the outside of the section B, and the valve 0 is held to its seat by springs s to prevent the escape of oarbureted air, and from the annular chamber 19 air is admitted to the vaporizing-chamber 0 through ports or passages t to mingle with the air supplied through nozzle a and its valve D. The up per end of the section B is provided with a screw-thread u to connect the vaporizer to the induction-pipe of a gasmotor.

Within the casing is a foraminous cone E, secured in concentric position by a flange 11, secured between the flanges e and g to spread the liquid into a thin sheet or film and comminute the air in its passage through the flue perforations in the cone, so as to present fine So or thin streams of air to the liquid to produce rapid carbureting of the air, and within the cone E is a conical deflector F, which extends down below the upper or terminal end of the nozzle to and prevents liquid entering the 1102- 8 5 zle after passing through the perforations in the cone E and directs the liquid into the chamber 0. The deflector is provided with a transverse bar 10, with the boss 00 of which the stem 3 of the valve D engages and limits 0 the upward movement of the valve.

Liquid is supplied to the vaporizer by a suitable pump, (not shown,) or by any suitable means used for the purpose, through tube G, which terminates above and adjacent to the 9 5 cone and directs the liquid upon the apex of the cone.

The main air-valve D and the supplemental air-valve o are opened by the inductionstroke of the piston of the gas-motor and closed automatically, the former by gravity and the latter by the spring 3.

Having thus fully described my invention, what I claim is 1. A device for vaporizing volatile liquids, comprising an outer casing, a foraminous cone within the casing and a liquid supply above said cone, in combination with an air supply below the cone.

2. A device for vaporizing volatile liquids, comprising an outer casing, a foraminous cone within the casing,a deflector within the cone and a liquid supply above the cone, in combination with an air supply below the cone and concentric thereto.

3. A device for vaporizing volatile liquids, comprising an outer casing a foraminous cone within the casing anda liquid supply above the cone, in combination with an air supply below the cone and provided with a check valve.

4;. A device for vaporizing volatile liquids, comprising an outer casing constructed to be connected at its upper end with the induction pipe of a gas motor and having a passage through the bottom of the casing to supply air, and a valve controlling said passage, in combination with a foraminous cone within the casing and above the air supply and an oil supply above and adj went to the apex of said cone. 1

5. A device for vaporizing volatile liquids, comprising an outer casing provided with means for connecting it with the induction pipe of a gas motor, an air supply in the bottom of the casing and having a flaring discharge end, a valve for controlling said sup ply, an annularliquid chamber and. a passage leading therefrom, in combination with aliquid supply, means for spreading the liquid into a thin sheet and diffusing the air through the liquid.

6. A device for vaporizing volatile liquids, comprising an outer casing, a foraminous cone within the casing, an air supply below the cone and provided with a check valve and a deflector, a guide and guard for the check valve, in combination with a liquid supply above the cone.

7. A device for vaporizing volatile liquids, comprising an outer casing, means for supplying liquid and means for spreading the liquid into a thin sheet and comminuting air, in combination with a main air supply at the lower end of the casing and a supplemental air supply near the upper end thereof.

8. A device for vaporizing volatile liquids, comprising an outer casing, means for supplying liquid and a foraminous cone to spread the liquid into a thin sheet and comminute air, in combination with a main air supply below the cone and a supplemental air supply near the apex of the cone.

9. A device for vaporizing volatile liquids, comprising an outer casing provided with a concentric air supply in its bottom, an annular supplemental air supply in the Wall of the casing and provided with a cut off valve and a check valve and aforaminous cone, in combination with a liquid supply above the cone.

10. A device for vaporizing volatile liquids. comprisinga two part conicalcasing, the lower section of which casing is provided with a concentric air supply nozzle extending above and below the bottom thereof, an annular liquid chamber around said nozzle a discharge communicating with said chamber and a valve seated upon the inner end of the nozzle. in combination with a deflector above and surrounding the valve, a foraminous cone above the deflector and a liquid supply above the cone.

In testimony whereof I affix my signature in presence of two witnesses.
